If you are going to post part of your log file, please also

your mod_jk configuration and version information.
I am using mod_jk 1.2.30 which I built from the source tarball.
My application just locked up so I did a tail -f
on the mod_jk log and made a request to it.
Here is what generated in the log:
[Fri Jun 18 15:30:17.614 2010] [394:47652193829632] [info]

Hmmm, errno 11 is often EAGAIN. What platform are you using (OS, version)?

jk_handler::mod_jk.c (2618): Service error=0 for worker=tomcat
I took a look at the tomcat catalina.out and do not see any errors there.
The CPU is empty and the RAM is available.
I telnet to 127.0.0.1 port 8009 on the machine, I get a connection,
so something is listening on the port.
If I do a ps aux | grep java, I see two processes for tomcat which is
normal.
I checked the mysql log and do not see any errors. I did a show innodb
status and do not see any deadlocks in the database.
I am attaching the properties for my jk configuation and a screen shot of
the
JK Status in case it helps.
What is really strange is the JK Status page says -48 connections. It seems
like that number should always be positive or zero but not negative.
That should be unrelated (and yes: it's not OK).

Rainer
